It is supposedly like Vim, intentional or not. It's contextual (Vim: command mode, insert mode, Blender: object mode, edit mode, etc.) and reverse-polish (e.g. "UVSphere 16 16"). It is an efficient, streamlined and, honestly, superior interface.

You cannot explore it, and that's the problem. RTFM is required.

Change aversion is a factor, but it also alienated complete newbies.
